Good point about the 6 month period.
I did not notice that. Probably should have asked since most go through the cyano phase during the initial cycle, and would advise to wait it out in that scenario.
As to your point about the water change being the actual cure: the cyano completely disappears BEFORE the water change so that can be ruled out. Also there is no evidence to support slime remover killing beneficial bacteria. Others wise you would see ammonia and nitrite spikes after the products use. I can see how logic would lead you to this train of thought, since I have also wondered how the mechanism to kill cyano can be so species specific.[/QUOTE
I was suggesting that if you have to do that many water changes to get your skimmer operating correctly why not do them before the use of the chemicals and the whole time keep your skimmer going and for go the use of any chemical. I am by no means suggesting it doesn't work just not necessary IME
There is no evidence that it doesn't kill some of the beneficial bacteria either. It would not necessarily trigger an ammonia spike either especially with all the water changes. I think the cyano is feeding on the hydrogen sulfide produced by the anaerobic bacteria that is cultured in the rock and sand bed and will subside once a balanced is reached between the bioload and the bacteria.
